0.5 mU/L represents the lower limit of the reference range for the TSH assay which can be 0.3–0.5
mU/L depending on the specific assay.

TSH target for patients with a biochemical incomplete response can be quite different based on
original ATA risk, Tg level, Tg trend over time and risk of TSH suppression.
